abstract
To take advantage of the astrophysical potential of Gamma-Ray Bursts (GRBs), Chinese and French astrophysicists have engaged the SVOM mission (Space-based multi-band astronomical Variable Objects Monitor). Major advances in GRB studies resulting from the synergy between space and ground observations, the SVOM mission implements space and ground instrumentation. The scientific objectives of the mission put a special emphasis on two categories of GRBs: very distant GRBs at z$>$5 which constitute exceptional cosmological probes, and faint/soft nearby GRBs which allow probing the nature of the progenitors and the physics at work in the explosion. These goals have a major impact on the design of the mission: the on-board hard X-ray imager is sensitive down to 4 keV and computes on line image and rate triggers, and the follow-up telescopes on the ground are sensitive in the NIR. At the beginning of the next decade, SVOM will be the main provider of GRB positions and spectral parameters on very short time scale. The SVOM instruments will operate simultaneously with a wide range of powerful astronomical devices. This rare instrumental conjunction, combined with the relevance of the scientific topics connected with GRB studies, warrants a remarkable scientific return for SVOM. In addition, the SVOM instrumentation, primarily designed for GRB studies, composes a unique multi-wavelength observatory with rapid slew capability that will find multiple applications for the whole astronomy community beyond the specific objectives linked to GRBs. This report lists the scientific themes that will benefit from observations made with SVOM, whether they are specific GRB topics, or more generally all the issues that can take advantage of the multi-wavelength capabilities of SVOM.

The COLIBRI telescope meets its design specifications for prompt GRB afterglow observations and subarcsecond localizations based on commissioning results.

Machine learning on precursor emission in 366 GRBs yields a simple prompt-only index EPI that separates merger-driven from collapsar-driven bursts at a threshold of 6.2.
Discovery and multiwavelength follow-up of EP J175257.3-351923, classified as a candidate black hole LMXB based on its 250-day FRED outburst, persistent hard state, truncated disk spectrum with ~217 keV cutoff, and flux ratios.
A sample of 169 magnetar-candidate long GRBs yields B_p proportional to P_0 to the power 0.83 and fields an order of magnitude stronger than those in superluminous supernovae.
The GRM on SVOM is a new wide-field gamma-ray detector that has operated successfully in orbit since June 2024, detecting more than 100 GRBs annually with performance cross-validated against GECAM and Fermi/GBM.
Long gamma-ray bursts imply a higher cosmic star formation rate density at z>6 than galaxy surveys detect, sufficient to drive reionization with moderate ionizing efficiency and escape fraction, implying a large population of undetected faint galaxies.

The SVOM/VT instrument reaches 22.5 AB mag sensitivity and detects about 80% of targeted gamma-ray bursts, outperforming Swift/UVOT and enabling high-redshift studies.
Solar axion-like particles up to 5.5 MeV produce off-axis MeV photons via two-body decay, enabling new space and terrestrial searches that could probe g_aγ down to 10^{-12} GeV^{-1}.

Atmospheric albedo contributes 10% to 100% of GRM effective area depending on Earth orientation and GRB angle, with dominance at 8-20 keV when direct response vanishes, requiring inclusion in calibration.
